What happens if you shift from 2nd to 3rd and then "D" using the shift point of 2600 rpm at each shift?

There is no such thing as an M1082. There is only the M1082A1. There is also an M1095A1 but it is a duel axle trailer. In case you cannot round up a manual, they come with ABS and tire inflation. The tire inflation works with any military truck and pumps the tires to 45-48 lbs. pressure. They...

This is a common problem. First check the sending unit. Otherwise, one must pull the dash cover. My most recent issue required removing the dash cover. I cleaned the connects and everything has been working well since.

Shell makes the Rotella T1, Heavy Duty Diesel Straight grade SAE 30 and SAE 10 motor oils. Advanced Auto and Auto Zone both carry the oils. I get them in one gallon packs of 3 to a pack. The old Mack ENDT-673 sitting in my M54A1 gets the SAE 30 eight months out of the year and the SAE 10 the...

Zinc and phosphorus. There are number of specific brands of additives on the market for this purpose. Lucas makes an oil with the additives included but it is for old high performance gassers. However, I use the Shell Rotella 15-40 and add the zinc and phosphorus with the oil change. Eastwood...

Fuel additive is one thing but in my opinion, the engine oils available for our diesel engines are far more important. My Mack ENDT-673 engine has flat-tappet lifters. One must add zinc and phosphorus to every oil change if one wishes to keep their engines healthy and especially under heavy...

The Staples printed stuff is not cheap especially if one gets all the manuals for one vehicle...operator's, maintenance, lube order, parts, depot maintenance can all be separate manuals. Some are shorter than other. One of the manuals for my M54A1 is over 600 pages. It gets expensive. However...

Dependable is a moving target. In my opinion, they were far better than the Continental gas engines and the M54A2 and M52A2 multi-fuel versions of the trucks. Like any other truck engine much depends on the driver(s). The Mack ENDT-s faired best when pushed hard and worked at the top of the...

The Mack 5-tons were produced 1965-70. Depot rebuilds ceased in 1975.

The Mack engines were the ENDT-673 of which there were three versions produced over the production years. #1-had five-ring pistons, 9/16-inch cylinder head studs, and metal bearings in the IP governor. #2-had four-ring pistons, 5/8-inch cylinder head studs, and Teflon bushed IP governor...

Try liberatedmanuals.com They are all free and with few exceptions, all there including multiple versions of the same TMs. I print mine at Staples and throw them in a hardbound notebook that will lay flat which can be easily viewed at the point of work.

In my experience with GP, I was offered and I accepted a cash settlement when the same thing happened to me last year. However, I continued the pick up after discovering it did not have the engine as stated. However, one should act before the expiration of the Iron Clad Policy with is not very...

Take another look rustystud. yes, the minimum bid was $3000 it was found on Tuesday. There were many other bidders but no others were "reserve met." However, after the auction was over tonight, all the bids in the entire auction suddenly became "Reserve Met" no matter what the bid, including...

Strange as it may seem, the 5-ton version of the multi-fuel is a whole different animal than the deuce version at least in the horsepower dept. The 5-tom version puts out 220 horsepower which is more than the Mack engine. The multi-fuel M54 is the M54A2

I have seen them offered by a few companies and individuals over the last year in the $5000-$7000 range. However, no one knows for sure if any were actually sold and at what price. One factor is whether the engine is set up for deuce or 5-ton operation. I have a 1975 Mack M54A1. There are times...

Warthog explains it well. However, if you have several accessories you want to add, your options become progressively more limited. On my deuce truck, I run cab marker lights, a pair of cab mounted Xeon lamps, two 24-volt cabin fans, a dome light, a charger, a 24-volt artic heater for the cargo...

There is a far better, safer way to split your 24-12 volt needs in MVs. It is what the military uses. It adds 8 additional 24-volt circuits and 4 additional 12-volt circuits. Each is fused with the amps required for the circuit. There is no heat byproduct and the overloading issue is never an...

Peashooter sold me four sets just last month, one deuce and three 5-tons. It takes up to a month but well worth it.
